interesting, I will have to look at their design?[/QUOTE
here is the email I received from frankenstein trikes:
Henry
You purchased the premium kit which includes the trike kit, the exhaust and the raked tree.
We do not sell fork tube extensions with our tree.
Some companies sell the fork tube extensions with their tree because of the way their trees are made.
I do not know if there are fork tube extensions available, if you were to find some and install them it would raise the front of the bike which would be lengthening the trail which could make the trike heavy to steer.
We only have one tree for the touring models.
I am not sure how the back of the trike could be higher than when it was a bike.
When our trike kit is installed the back of the bike is lowered less than ½”
When the trees are installed on the front, the front is lowered less than ½”
The height of the wheels and tires are very close to the height of the motorcycle wheel and tire.
